A digraph is a combination of two letters that represent one sound. Common examples include 'sh', 'ch', 'th', and 'ph'. It's like two letters teaming up to become one vocal unit. Think of it as a superhero duo. For instance, 'ph' makes the 'f' sound in 'phone.' Without knowing digraphs, reading could be tough. So, they are key in decoding words.
